Reactions of lithiated heteroaryl- (or aryl-) methylbenzotriazoles 4a-e with heteroaryl (or aryl) esters 5a-f give alpha-benzotriazolyl ketones 6a-n in average yields of 90-95%. Oxidation of ketones 6a-l in aqueous DMSO in the presence of oxygen and sodium bicarbonate gave heteroaryl- (aryl-) 1,2-ethanediones 7a-l in average yields of 60-80%.
